l To all whom t may concern.'

-Be it known that I, WAYNE E. DUNs'roN, a citizen of .the United States,` residing at Kalamazoo, in the county of Kalamazoo' and State of Michigan, have invented a certain new and useful Improvement in Automobile Bumpers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to bumpers for automobiles and similar vehicles, and more articularly to the means whereby the said umpers are connected to and supported from the brackets or arms which in turn are supported from the front ends of the side sills of such vehicles. It is the general purpose and object of this invention to provide a connecting device for this purpose which may be conveniently and economically produced (preferably from pressed metal), and which is capable of performing its functions in an eicient manner. I accomplish the foregoing objects in and Jthrough the construction shown in the drawings forming a part hereof, wherein Fi 1 represents a plan view of a bumper an of. its supporting arms and having my invention applied thereto; Fig. 2 is an enlarged sectional de tail corresponding to the line 2-2 of Fig. 1; 3 a sectional detail corresponding to the line 3 3 of Fi 2; and Figs. 4 and 5 views in elevation o the blanks from which the two members of my fitting are constructed. Describing thev various parts herein by reference characters, 1 denotes the front bar or plate and 2 the rear bar or plate` of a double bumper of the flat spring-leaf type, the front and rear bars being shown as connected by rearwardly extending curved loops 2B. The bumper is supported from the vehicle frame (not shown) by a pair of arms, indicated at 3, each arm having at its outer end a sleeve or eye 4, the length of said sleeve or e e being approximately equal to the width o the bumper plate 2 which it lsu ortsil I i f h orteur eososuport' te bumper platg rpdii the ends of Ithe 1iiirtins 3,

I employ with each arm a pair of ressed steel clamping members, the bla for which are indicated at A and B, Figs. 4 and 5, respectively. Oneend 5 of the blank B is substantially triangular inoutline and is pvided with a 'single aperture while the y 6 is widened and Vis provided with a pair of. apertures 7. The blank A is generall'y slmilar in shape tothe blank B and is provided with a triangular end 8 and a body 9 similar in outline to the body 6 and havin openings 8"a'nd 9 `adapted to register wit the ope 5 and 7, res lvely. In addition, the blankB is rovi ed-with a central rojection 10 also aving an aperture 10 t erethrough. For convenience of de-- scription, th'e clamping member formed from the blank B will be referred to as the outer member and the clamping member formed from the blank A will referred to.A

as the inner member.

The upper or reduced end of the outer member 1s bent at substantially riglht angles to the body thereof, forming the orizontal portion 5 having the aperture 5 and the vertical bodyl portion 6 havin the apertures 7 in the bottom thereof (seey igs. 2 and 3). The reduced upper portion ofv the'blank A is bent at substantially right angles to the body thereof, forming thehorizontal portion 8 having the aperture 8 therein while the body portion 9 extends vertically, having the apertures 9a therein adapted to register with the apertures 7. The ton e 10 is bent horizontally, as indicated in igs. 2 and 3, with its aperture 10a in substantially vertical alignment with the apertures 5a and 8.

The inner U-shaped member (comprising the parts 8, 9 and 10) will be slipped upon the sleeve or eye 4 with the holes 8a and 10* registering with the bore of said sleeve. The

bumper 2 will be applied to the vertical body .portion 9 and the outer clamping member will be applied in the manner shown in the drawing, with its horizontal portion 5 restpart 5 to the said bolts, being equal to the width of the bumper plate, whereby the top Iof the plate 'can bearvagainst the horizontal portion 5 of the outer member while its bottomis supported upon 'the bolts 12.

It will be understood that the bumper shown herein is merely illustrative and that mty clamping @vice may be employed with o er and various forms of bumpers without avoiding the spirit of my inventlon.

i Having thus described my invention, what I claim is:

1. The combination, with a member having a sleeve or eye thereon, of a bumper bar and means for securing the same to said sleeve or eye, the said means comprising an inner U-shaped member adapted to receive said sleeve or eye between the ends thereof and having openings in such ends adapted to register wlth the bore of such sleeve or eye, an outer L-shaped member having in one of its branches an opening adapted to register with the opening in t-he first mentioned member, a bolt extending through said sleeve or eye and said openings, and one or more bolts connectin the intermediate portion of the first mem er and the other branch of the second member, the body portion of the second member being s aced from the body portion of the first memlber 'to provide a space therebetween for the reception of said bar. i

2. The combination, with an arm having a sleeve or eye thereon, of a bumper bar 'and means for securing the same to said sleeve or eye, the said means comprising an inner U- shaped member adapted to receive said sleeve or eye between the ends thereof and having openings in such ends adapted to register with the bore of such sleeve or eye, an

, outer L-shaped member having in one of its branches an opening adapted to register with the opening in the first mentioned member and shaped and proportioned to provide a slot with the first member, a bolt extending through said sleeve or eye and said'openings, and means connecting the intermediate portion of the first member and the other branch of the second member.

3. The combination, with an arm having a sleeve or eye thereon, of a bumper bar and means for securing the same to said sleeve or eye, the said means comprising an inner U- shaped member adaptedl to receive said sleeve or eye between the ends thereof and having openings in such ends adapted to register with the bore of such sleeve or eye, an outer member comprisinga body portion and a portion bent at an angle thereto and provided with an opening adapted to register with the openings in the first member, the second portion of the second member bein of greater length than the corresponding en portion of the first member to provide a slot therewith, the body portions of said members being provided with aligned apertures, and one or more bolts in said apertures connecting the body portions of. said member.

retenes 4. The combination, with an arm having a sleeve or e'ye thereon, of a bumper bar and means for securing the same to said sleeve or eye, the said means comprising an inner U- shaped member adapted to receive -said sleeve or eye between the upper and the lower ends thereof and having openings registering with the bore of such sleeve or eye, an outer member comprising an upper body portion and a portion bent at an angle thereto and provided with an opening adapted to register with the openings in the first member, the upper portion of the second member being of greater length than the upper end portion of the first member to provide a vertical slot therewith, the body portions of said members being provided with aligned apertures in the lower ends thereof, and one or more bolts in said apertures connecting the body portions of said member and extending across the bottom of said slot.

5. rihe combination, with an arm having a sleeve or eye thereon, of a bumper bar and means for securing the same to said sleeve or eye, the said means comprising an inner U-shaped member adapted to receive said sleeve or eye between the ends thereof andhaving opening: in Such ends adapted to register with the bore of such sleeve or eye, the lower end of the body of said member having one or more apertures therethrough, an L-shaped outer member having an upper portion adapted to overlap the u er end of the first member and provlde'd wit Van aperture adapted to register with the aperture in such. first member and having abody portion spaced from the body portion of the first member and provided at its lower end with one or more apertures adapted to register with the aperture or apertures in the body of the first member and bolts extending through apertures in the bodies of the said members.

6. rihe combination, with an arm having a sleeve or eye thereon, of a bumper bar and means for securing the same to said sleeve or eye, said means comprising a member adapted to be secured to opposite ends of said sleeve or eye and a second member adapted to be secured at one end to said sleeve or eye and to the first member and to form a space with the first member for the reception of said bar, and means for clamping the said members against said bar andthe other end of the second member tothe corresponding part of the first member. v

in testimony whereof, I hereunto aiiix my signature.
